ARITY is not documented
-----------------------
Key: PIG-971
URL: https://issues.apache.org/jira/browse/PIG-971
Project: Pig
Issue Type: Bug
Components: documentation
Affects Versions: 0.3.0, 0.3.1
Reporter: Bogdan Dorohonceanu
ARITY is not documented in Pig Latin Manual:
http://hadoop.apache.org/pig/docs/r0.3.0/piglatin.html
It is only 1 time mentioned in FAQ:
"Q: How do I prevent failure if some records don't have the needed number of
columns?
You can filter away those records by including the following in your Pig
program:
A = LOAD 'foo' USING PigStorage('\t');
B = FILTER A BY ARITY(*) < 5;
.....
This code would drop all records that have fewer than five (5) columns."
